As the heroes prepare to assemble, we look back on previous films
'nuff said: The Asgardian hero came to life this summer with Chris Hemsworth in the title role, and Natalie Portman, Stellan Skarsgaard and Anthony Hopkins along for the ride. The character will be included in "The Avengers," with Loki (Tom Hiddleston) acting as the film's primary villain. SHIELD agent Coulson (Clark Gregg) and future Avenger Hawkeye (Jeremy Renner) also appeared.
